At the moment, it may be difficult to imagine, but many people believe that, by the year 2100, we will live on the planet Mars．Our own planet, Earth, is becoming more and more crowed and polluted．Luckily, we can start again and build a better world on Mars．Here is what life could be like．
First of all, transport shouldnbe much better．At present, our spaceships are too slow to carry large numbers of people to Mars－it takes months．However, by 2100, spaceship can travel at half the speed of ligh．It might take us two or three days to get to Mars!
Secondly, humans need food, water and air to live．Scientists should be able to develop plants that can be grown on Mars．These plants will produce the food and air that we need．However, can these plants produce water for us? There is no answer now．
There is a problem for us to live on Mars．Mars pukkss us much less than the Earth does．This will be dangerous because we could easily jump too high and fly slowly away into space．To prevent this, humans on Mars have to wear special shoes to make themselves heavier．
Life on Mars will be better than that on Earth in many ways, People will have more space．Living in a large building with only 10 bedrooms is highly possible．Many people believe that robot will do most of our work, so we have more time for our hobbies．
There will probably be no school on Mars．Every studetn will have a computer at home which is connected to the internet．They can study, do their homework and take exams in online schools．Each student will also have their own online teacher called“e-teacher”．
However, in some ways, life on Mars may not be better than that on the earth today．Food will not be the same－meals will probably be in the form of pills and will not be as delicious as they are today, Also, space travel will make many people feel ill．The spaceship will travel fast but the journey to Mars will probably be very uncomfortable．

You will have a lot of reading to do in this grade this year．You can do more of it in less time if you learn to read rapidly．
Perhaps you have been told about some habits (习惯) which keep a person from reading fast and have been strongly asked to break those habits which you might have．
Do you still have any of these bad habits?Check yourself by answering“yes”or“no”to these questions．
(1) Do you move your lips (嘴唇) when reading silently?
(2) Do you point to words with your finger as you read?
(3)Do you move your head from side to side as you read?
(4)Do you read one word at a time?
If you answer“yes”to any of these questions,start at once to break the habit．If you move your tips，hold your fingers over them，or hold a piece of paper be-tween your lips while you are reading．Then if your lips move，your will know it and can stop them．
If you point to words，hold the two sides of your book，one side with your left hand，the other side with your right hand．Then you won't have a free finger to use in pointing while reading．If you move your head，place your chin (下巴) in one hand and hold your head still (静止不动的)．
If you read no more than one or two or three words at a time，you need to work very hard in learning to take in (吸收) more words at each glance (一瞥) as your eyes travel across the lines of words．
Even if you do rather fast now，you can learn to read even faster．As you probably have been told，the secret of fast reading is to take in whole groups of words as each glance．Read in through groups and force (迫使) your eyes along the lines of words as fast as you can to make them go．Anyone who practices doing these things will he able to read faster．
